This invention relates to novel devices and particularly to audible devices of a decorative nature and finding especial uses at the Christmastide and other festive occasions. In one of its more specific aspects the invention is directed to novel compact assemblies which may be coupled with electric sockets.

The most prevalent electric socket in use is the so-called standard screw socket which in general consists of an inverted cup-shaped insulator having a central button-contact and a threaded shell-contact therein and insulated from each other. These contacts are respectively connected to the leads or conductors connected to a source of electric energy. These sockets are standardized in the particular sizes in which they are used, as for example, the miniature, regular, mogul, etc.

Briefly, this invention is directed to devices which are unitary assemblies which may be demountably secured to said sockets in the same general manner as are the ordinary electric incandescent lamps. Each of the novel devices comprises a base having a pair of contacts and adapted to be inserted in and connected to an electric socket, a solenoid winding electrically connected to said contacts, a bell element supported by said base, a striker element, and means controlled by the energization of said solenoid for actuating one of said elements.

Fig. 1 is a view partly in section to illustrate a standard screw socket and an embodiment of the invention coupled with the socket.

Fig. 2 is a view partly in vertical section of an embodiment of the invention.

Fig. 3 is a View similar to Fig. 1, but showing an interruptor in the socket.

Fig. 4 is a view similar to Fig. 2, but showing an interruptor as part of the assembly.

As shown in the drawings, there is illustrated a conventional lamp socket comprising an insulator housing I carrying a central button metal contact II and a threaded shell metal contact I2. The contacts II and H. are insulated from each other and are electrically connected to conductors l3 and M, which are also connected to a source of electric energy.

The novel embodiment of the invention shown in Fig. 1 comprises a screw base 20 which has a hollow screw shell metal contact 2| and a central metal contact 22 insulated from contact 2|. The shell contact 2| terminates in a knurled flange 23 of insulating material. An insulating disc 25, having a central opening therethrough, is snapped into the lower open end of the hollow 2 shell contact 2| and is frictionally maintained in position thereat. Mounted on the disc 25 and located in the shell 2| is an insulating spool 28 carrying a solenoid winding 28. Mounted on the spool 26 and located in the shell 2| is an insula- V tor spacing collar 30 having a spring metal contact 3| coupled therewith. An elongated movable core 32 extends through the central opening in the-spool 26 and disc 25 and has a pair of stop flanges 34 and 35. One terminal 36 of the winding 28 is electrically connected to the shell 2| and its other terminal 3'! is electrically connected to the spring contact 3|. Flange 34 is composed of insulating material.

A loop 40 extends downwardly from the flange 23'. ,A bell element 42 having a free swinging striker element 43 suspended from the upper part thereof has a loop 44 at the central upper part thereof. It is to be understood that bell and striker elements other than the type shown may be employed. The conv'entionalspherical bell with a ball striker therein and commonly called a sleigh bell may also be used. The loop All extends through loop 44 so that the bell and striker element are supported by the base 20 for free swinging movement. Coupled to the lower end of the core 32 is an end of a flexible strin or cord 46, and the other end of string 46 is coupled to one side of the bell element 42.

In another illustrative embodiment of the invention, as shown in Fig. 4, an interruptor 50 is located in the base 20. A terminal of interruptor 50 is electrically connected to contact 22 and its other terminal is electrically connected to the spring contact 3|. In this embodiment the solenoid winding 28 in series with the interruptor 50 and the contacts 2| and '22 of base 20.

Both of the assemblies shown in Figs. 2 and 4 are compact combinations and either of them may be inserted in and demountably connected with the standard screw socket in the same manner that a screw base lamp is so connected thereto. The embodiment shown in Fig. 3 may be directly connected to such a socket whose terminals are connected to a source of electric energy as shown in Fig. l, where the contact 2| is electrically connected to the shell l2 and the contact 22 is electrically connected to contact I|.

Instead of having the interruptor 50 as part of the assembly as shown in Fig. 4, the interruptor 50 may be placed in the socket as a separate element and then the assembly shown in Fig. 2 may be coupled therewith, as shown in Fig. 3. If desired, the assembly shown in Fig. 2 may be coupled with the socket as shown in Fig. l and 3 the interrupter 50 may in this instance be located outside of the socket and base and be in series with the source of electric energy.

The interruptors 50, employed in the various manners heretofore set forth, are electrothermal 5 responsive devices and are preferably of the bimetallic type which, due to the rise in temperature of their bimetallic element upon passage of current in the circuit including the solenoid windings, automatically breaktliatici-rcuit and upon cooling makethe circuit. Interruptors for making and breaking a circuit are well known and for my purposes I may employ those known as the Twinkle-Button type-i:

When these various combinations are connected to a source of electric energy as iound in the ordinary home, passage ofcurrent takes place in the circuit in which the interrupter 5B)" the contacts and solenoid winding 28 are inele'ce trical series relationship.
